I have an old (about 5 yrs) Mongoose Hill Topper. I want a new bike, but cannot afford one, so this is what I was thinking, let me know what you think. I am thinking of piece by peice changing this bike until it is a new one. Example, first I will change out the solid forks to shocks, then later when can afford will replace wheels, then will replace crank and drive, then later on I can change the frame and shift system. Thinking this will take about 2 years to do piece by piece so I can afford it. A) Is it a good idea? B) Will it work?
